Abstract

The invention discloses an information receiving and sending method, terminal and network equipment. The information receiving method includes: receiving indication information, the indication information indicating at least one transmission control information TCI status of a demodulation reference signal DMRS port on one or more resources allocated to the terminal; determining one or more The corresponding relationship between the at least one TCI state on the resource and the code division multiplexing CDM group to which the DMRS port belongs; according to the correspondence between the TCI state on one or more resources and the CDM group to which the DMRS port belongs relationship, receiving information. The scheme of the present invention can determine the corresponding relationship between the CDM group and the TCI, thereby improving the reliability of transmission.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method for receiving and sending information, a terminal and a network device. Background technique [0002] In order to improve the coverage of the cell edge and provide a more balanced service quality in the service area, coordinated multi-point is still an important technical means in the NR system. From the perspective of network morphology, network deployment in the form of a large number of distributed access points + baseband centralized processing will be more conducive to providing a balanced user experience rate, and significantly reduce the delay and signaling overhead caused by handover. . With the increase of frequency bands, from the perspective of ensuring network coverage, relatively dense deployment of access points is also required. In the high frequency band, with the improvement of the integration degree of active antenna equipment, i...
